LOCOHOTIVE DRIVING-BOX STRUCTURE.

Application filed February 12, 192i. Serial Ref t 44,565.

This invention relates to locomotive driv ing boxes and has special reference to an ar with indicator rods in place, without disturbing or removing the driving box spreader or dismantling the cellar and the contained parts.

Another object of the invention relates to the provision of improved means for holding the cellar and the end plate in position whereby the pin, which secures the same, cannot be distorted. This frequently occurs in standard arrangements now in use and is a source of annoyance and'expense because the distorted and jammed pin must be re moved in order to withdraw the cellar or tosupply fresh lubricant, and new pins must ordinarily be substituted forthe distorted ones. a

Still another object. of the invention resides in the provision of an arrangement whereby, when the locomotive is lifted with driving wheels in place, no load is imposed i on. the cellar, as is the case in standard eonstructions. The breakage of the cellar box which frequently results from this cause in standard constructions is thus eliminated.

' My invention also contemplates an improved arrangement whereby the parts may be readily adjusted to compensate for changed conditions resulting from wear, as will further appear.

The foregoing, together with such other objects as may hereinafter appear, or are incident to my invention, Iobtain by means of a construction which I have illustrated in preferred form in the accompanying drawings, wherein:

Fig. 1 is a side elevation of a driving box equipped with my improvements, such im: provements being shown in section on the line 11 of Fig. 2; Fig. 2 is a section through my improvements taken on the line 22 of Fig. 1; Fig. 3 is an end elevationof the parts shown in Fig. 2 as applied to a box; Fi 4 is an end elevation of my improved orm of spreader as seen when looking at the left hand end of Fig. 2; and Fig.

5 is a fragmentary section illustrating a modification of my invention.

Referring now to Fig 1, the reference number'7 indicates the driving box which has the usual brass 8 for the axle 9.. The jaws of the driving box are held against pinching or inward flexure under load, b the spreader indicated erence letter A, the construction of which will shortly be described. The driving box cellar is indicated by the reference number 10 and it may be of any preferred general construction, such, for example, ;as illustrated in the United States patent to Martin, 1,268,748 of June 4, 1918. The driving box cellar 10 has the usual follower plate 11, lubricating spring 12 and lubricating pad 13. The grease cake is inserted between the follower plate 11 and the lubricating pad and the condition of the cake is indicated by the rods I l-which depend below the bottom of the cellar. 4

The spreader A comprises an open frame, substantially rectangular in shape, and it is secured to the box at its outer edge next to the driving wheel with a single long bolt 15. The separation of the transverse compresslon-resisting portions or members of the frame affords opening for downward projection, and observation, of the indicating rods 14. It is secured atits inner edge next as a whole by the re The cellar 1O rests upon the top of the I spreader and near its outer side it is provided with a depending lug 18 (see Fig. 2) which abuts against a side of the spreader and limits the outward movement of, the cellar.

The cellar is maintained in position by the end plate 19 which also serves to close the open end of the cellar. The closure plate 19 is held in position by a single pin 20 which passes through the lugs 21 and 22 on the in nor face of the member 17 of the spreader (see Figs. 2 and 3). The end closure plate 19 is also provided with a pair of ears 21 and 22 which are grooved as at 23, such grooves coming into alignment with the pin apertures in the lugs 21 and 22 when the end closure plate is brought in proper position. When thepin is in position the closure plate will be securely held against vertical movement and also against movement away from'the spreader. The closure plate is also held as against displacement across the face of the spreader and cellar.

The shoulders 24 and 25 on che. closure plate respectively are adapted Bo-,rest on the lugs 21 and- 22 thereby relieving 'the' pin 20- ofload, particularly when the locomotive is lifted with the drivers in place. 'It will be seen that when this is done. theend closure which are concave at the top to fit plates, the axle, will take the load of the axles and drivers and transmit thesame directly to the lugs 21 and 22 of the spreader. There is thus no tendency to distort the pins 20 and the diiiiculties heretofore noted are avoided. /In order to withdraw the cel ar or to 1nser-t a new grease cake, it is only necessary to remove the pin .20 by withdrawing the key 27 whichwill permit of the removal of the closure plate 19. No other parts need be disturbed.

By carrying the closure plate 19 upwardlv a little farther than the front wall of the cellar, the end closure plates will relieve the cellars of all load, when the locomotive is lifted'with drivers in place and the breakages frequently occurring in standard practice where the load is taken by the cellars,

-modification shown in Fig. 5, from inspe'c-' tion of which it will be seen that the end i closure plate 19 is supported on the member 17 by either one of two lugs 28 and 29, ar-

ranged on opposite sides of the plate in stepped relation. When the plate is reversed and it rests-upon the lug 29 it will be seen that it will be shifted upwardly, thuscompensating for the letting down of theibbxabove referred to and ensuring the maintenanceof the lubricating pad in place. I claim:

l. The combination with a laterally removable driving box cellar having a grease follower plate and indicator rods p'roject-' ing there elow, of a driving box spreader for resisting inward flexure of the box jaws and means for securing it in position, the

spreader and the securing means being so constructed and disposed as not to interfere, when in position, with the removal of the cellar with its indicator rods.

2. The, combination with a driving box having a removable lubricating cellar with indicating means projecting therebelow, of a spreader for resisting inward ,flexure of the box jaws recessed at its upper side to afford passage for the aforesaid indicating means when the cellar is shifted-away from the adjacent driver to remove it from the box, and separate means for securing the cellar to the respective pedestal jaws.
